i wasnt aware that every single picture went onto google images. can you set them up to be not indexed on most sites?

When you join a social site there are options for privacy.
The social sites tend to turn off privacy by default in order to market their site ! Facebook were/are by far the worst courtesy of being the most successful

That is not googles fault. Google just happens to be the financial enemy of Apple and Microsoft.
So Apple sues and Microsoft campaigns for our privacy!
